Thanks for the Help Regina, below are some of the points I attempted. setsrid(MakePoint(834934.2263,26712690.6089, 32107) setsrid(MakePoint(834533.210694,26712881.1962, 32107) setsrid(MakePoint(834224.086891,26712318.3331, 32107) Is there a way to check if it is in the range of the projection?
From: [EMAIL PROTECTED]: [EMAIL PROTECTED]: RE: [postgis-users] Need Help with TransformDate: Fri, 5 Sep 2008 18:19:58 -0400 RH, This kind of thing happens if your input points are not actually in the projection you say they are with setsrid. Give us an example 32107 point you are using. I suspect it doesn't fall in the range of a valid 32107 point. Hope that helps, Regina From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of R HSent: Friday, September 05, 2008 1:13 PMTo: [EMAIL PROTECTED]: [postgis-users] Need Help with Transform Transform is returning to the same value, for different inputs? Below is what I have done... select AddGeometryColumn('data_stage', 'table', 'geo4269', 4269, 'POINT', 2)select AddGeometryColumn('data_stage', 'table', 'geo32107', 32107, 'POINT', 2) update tableset geo32107= setsrid(MakePoint(x, y), 32107) where .... update table set geo4269 = transfrom(geo32107, 4269)where ....column geo4269 all have the same vaule. select AsText(geo4269) returns 'POINT(-115.583333333333 90)' for all rows. And select AsText(geo32107) returns the point as input. Am I using transform wrong? Or any other problems? Any help many thanks...
